BACKGROUND A recent study using a rat model found significant differences at the time of diabetes onset in the bacterial communities responsible for type 1 diabetes modulation. We hypothesized that type 1 diabetes in humans could also be linked to a specific gut microbiota. Our aim was to quantify and evaluate the difference in the composition of gut(More)
The biological properties of dietary polyphenols are greatly dependent on their bioavailability that, in turn, is largely influenced by their degree of polymerization. The gut microbiota play a key role in modulating the production, bioavailability and, thus, the biological activities of phenolic metabolites, particularly after the intake of food containing(More)
BACKGROUND Several evidences indicate that gut microbiota is involved in the control of host energy metabolism. OBJECTIVE To evaluate the differences in the composition of gut microbiota in rat models under different nutritional status and physical activity and to identify their associations with serum leptin and ghrelin levels. METHODS In a case(More)
BACKGROUND FABP4 is predominantly expressed in adipose tissue, and its circulating levels are linked with obesity and a poor atherogenic profile. OBJECTIVE In patients with a wide BMI range, we analyze FABP4 expression in adipose and hepatic tissues in the settings of obesity and insulin resistance. Associations between FABP4 expression in adipose tissue(More)
Serum transaminase levels (serum glutamic-oxaloacetic transaminase or serum glutamic-pyruvic transaminase) were found to be altered in 40 (21.39%) of 187 patients with oral lichen planus. The patients with oral lichen planus who had altered transaminase levels were on average older than those without liver disorders and exhibited a higher percentage of(More)
OBJECTIVE We compared the levels of biomarkers of oxidative stress before and after a fat overload in three groups. MATERIALS AND METHODS 17 controls and two groups with hypertriglyceridemia: 43 without the metabolic syndrome (TG-non-MS) and 29 with the metabolic syndrome (TG-MS). All subjects underwent a 60 g fat overload. Baseline measurements included(More)
Obesity and its associated disorders are a major public health concern. Although obesity has been mainly related with perturbations of the balance between food intake and energy expenditure, other factors must nevertheless be considered. Recent insight suggests that an altered composition and diversity of gut microbiota could play an important role in the(More)
OBJECTIVE Previous studies have demonstrated that the lower renal excretion of urates in patients with hyperuricaemia is inversely related to plasma very low-density lipoprotein (VLDL) levels, and the different genotypes of the apolipoprotein E gene are related to the plasma levels of lipids. The aim of this study was to determine the prevalence of(More)
Activation of the PPAR gamma 2 gene (PPARG2) improves the action of insulin and its lipid metabolism. We examined the association between Pro12Ala polymorphism of PPARG2, type 2 diabetes mellitus (DM2), and peripheral insulin sensitivity in a population with a high intake of oleic acid. A cross-sectional, population-based study was undertaken in Pizarra, a(More)
Sleep apnea-hypopnea syndrome (SAHS) is characterized by recurrent episodes of hypoxia/reoxygenation, which seems to promote oxidative stress. SAHS patients experience increases in hypertension, obesity, and dyslipidemia, and the oxidative state has been related to the genesis of these disorders. The purpose of this study was to examine the changes in(More)
